For oil refining and chemical industry, heating furnace temperature is relatively high, the maximum capacity of 1350 ℃. Ceramic fiber material has not been previously approved design and the owners, the conventional design of the furnace walls and roof of the working surface is substantially the severity of refractory castable, lightweight insulation bricks and other materials, the thickness of the lining layer is generally higher than 300mm . Following major drawbacks: the total amount of refractories not only bulky and too heavy, the whole furnace refractories total of about 600T above, to the furnace materials procurement and on-site construction brought great difficulty; the furnace walls and roof anchor brick hanging very inconvenient, not easy leveling; castable construction process requires on-site support template leaving in expansion joints, long construction period; need to follow the material itself characteristic curve ovens, steel usage is relatively large, and heating furnaces and other heating and cooling speed is limited. In summary, the traditional way of high-temperature furnace masonry there are many defects, must be improved and perfected. Practice shows that in order to replace the traditional heavy ceramic fiber refractory lining material for high temperature furnace wall, the prospects are very bright. Ceramic fiber as an energy efficient fibrous material, according to its use at different temperatures, can be divided into the following categories: common type (950 ℃), Standard (1000 ℃), high-purity type (1100 ℃), high-alumina type (1200 ℃), aluminum zirconium type (1250 ℃), zirconium-containing (1300-1350 ℃) and polycrystalline mullite type (about 1350-1400 ℃) and other species. In accordance with the form of ceramic fiber products can be divided into cotton, blankets, carpets, plates, paper, cloth, tape, rope, modules, fiber and fiber castable spray paint and other forms. Ceramic fiber is a gradient using a variety of different temperature and furnace atmosphere of adaptability and other characteristics of the products, high-temperature furnace for use in different parts of different grades of ceramic fiber products offer a number of options to make the whole design and construction of fiber high-temperature furnace lining structure made possible by the estimates indicate that the cost of using ceramic fiber furnace in a slight decrease compared with traditional heavy refractory costs. This is a high temperature furnace to further promote the use of ceramic fibers opened up a vast world. Many use Design Institute, Shandong Luyang AG produced several sets of high temperature ceramic fiber furnace practice in this regard have been made, and achieved significant energy savings. Construction method using ceramic fiber products generally are the following ways: a layup, modular type, veneer type, fiber coating type, style and other kinds of fiber castable. Shop type refractory fiber lining layer (1) structural characteristics: type of lining layer is laid ceramic fiber blankets, carpets, plates or other products in accordance with the requirements of the laying of the final thickness of the anchors to be used in the furnace wall plate fixation of an all-fiber Lining Structure way. This class is the first application of the lining, the most traditional kind of wall lining structure, its structural features roughly summarized as follows: A. You can select from different materials, the bulk density of the ceramic fiber insulation products composed of economic structure based on layers of operating temperature. B. fiber direction parallel to the direction of heat transfer and the furnace wall, the wall lining good insulation properties, can reduce heat loss wall lining. C. fiber lining the walls with large-sized ceramic fiber blanket (or felt) for the construction, only construction speed, and less furnace wall joints, improve shop floor wall lining insulation performance and energy efficiency. (2) designed for use in Attention:. A. layup type fiber wall lining anchors directly exposed to the hot surface of the furnace wall, although you can use heat-resistant steel or ceramic anchors quality, but it still limits kinds of fiber wall lining of the use of temperature. Generally only suitable for temperatures below 1000 ℃. B. prone to peeling layer layered blanket laying fiber wall lining erosion robust performance, general furnace air speed over 10m / s. C. completely when the layers were laid fiber blanket, anti-erosion performance is poor, using the plate / blanket composite wall structure after lining can improve the performance of anti-erosion. D. Because anchors directly exposed to the work of the hot surface, heat-resistant alloy steel anchors using lower temperatures for high temperature, the anchors are easily damaged, and the use of ceramic anchors, anchor due to brittle ceramic thermal shock resistance poor, can not long-term use, need frequent replacement, at the same time, compared to ceramic and stainless steel anchors anchors, the price is relatively high. Therefore, laying ceremony fiber lining layer can be applied to 1000 ℃ below the furnace wall lining, such as crude oil distillation, hydrogenation. However, due to the structural characteristics of the limitations of the shop floor, so the furnace application is relatively less, but in terms of pipe insulation can flourish. In addition, how to find both high temperature, high strength, good thermal stability, excellent thermal shock resistance of the anchor is an effective way to broaden the shop floor type fiber lining applications. Modular fiber lining: modular structure of the lining is a ceramic fiber blanket folded into a certain width organ like fiber module, and then the fibers collapse block to be a certain amount of compression, and to be tied up in a compressed state, while embedded anchor ( Some are not embedded directly fixed at the construction site) consisting of fiber module, then connect the fixed structure of a fibrous wall lined with a variety of forms in the furnace shell plate welded metal anchors. The advantages of the modular structure of the fiber wall lining is: A. the construction is simple, easy to install, save time, the fiber wall repair, no large-scale demolition, simply replace the damaged parts of the fiber module can quickly resume production. B. fibers in the processing module, taken pre-compression, to compensate for shrinkage of the component at high temperatures, not only reduces the amount of heat shrinkage fiber wall lining, at the same time, the same conditions than traditional layup formula wall lining can be increased by using a temperature of 50 ℃ . C. has excellent resistance to weathering performance, the traditional shop-type fiber lining layer below 900 ℃ anti-erosion performance of up to 10m / s, while the modular fiber lining allows the anti-erosion performance of up to 30 m / s. D. anchor fiber module is not exposed to the fiber wall lining hot face, without using an expensive heat-resistant alloys, and nitrides and other ceramic materials for the anchor, saving investment while reducing heat transfer, but also to extend the use of anchor lifetime. Because of this structure has many advantages, so the application in the petrochemical industry, ethylene cracking furnace, reformer, hydrogen furnace, furnace and more widely. Veneer type fiber lining: (1) The structure and characteristics: veneer type fiber lining is made of fibers with fiber blanket strip bundle, and then through the high temperature in the furnace wall adhesive paste to get a good fire-resistant insulation lining structure. Its advantages are: A. combined use with other refractory materials, can significantly enhance the insulation effect. B. can arbitrarily select the relevant parts of the furnace construction, to facilitate construction. C. has chosen to use, can greatly reduce the cost. Designed for use in question should be noted: A. plate combined with a lack of both a solid, mature and high temperature, ideal binder, appeared after the existing adhesive paste veneer components in use off phenomenon. B. veneer lining maximum thickness of only 50mm, small thickness, can not be used alone as a lining, can only be used with other lined composite. C. fiber veneer strips assembly poor flexibility, between two adjacent components of the weak ability to compensate. Outside of the structure present in the petrochemical ethylene cracker furnace only individual applications, such as high-temperature furnace crystal fiber veneer blocks to enhance high temperature performance fiber materials, other grades of veneer blocks petrochemical furnace application is not a lot. |
